SCOPE OF THE INVENTION

The foregoing description sets forth various embodiments of formulations, methods, procedures and practices for reducing or preventing the development, or the risk of development, of neuropathology as a result of traumatic injury. Insofar as such formulations, methods, procedures and practices contain one or more functions or operations, it will be understood by those within the art that each formulation, method, procedure and practice can be implemented, individually or collectively, within a wide range of many combinations without undue experimentation.

A person having ordinary skill in the art will recognize that, in one significant aspect, the herein described formulations (e.g., any combination of any two, any three or all four of gabapentin, progesterone, aprepitant and lithium), methods, and procedures and practices, and the discussion accompanying them, are used as examples for the sake of conceptual clarity and that various methods, procedures and practices are within the skill of those in the art. Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar herein is also intended to be representative of its class, and the non-inclusion of such specific formulation components (e.g., gabapentin, progesterone, aprepitant and lithium), methods, and procedures and practices herein should not be taken as indicating that limitation is desired.

It is generally contemplated that the formulations according to the inventive subject matter will be formulated for administration to a mammal, and especially to a human, having a condition that is responsive to the administration of such a formulation. Therefore, where contemplated formulation compounds are administered in a pharmacological composition, it is understood that contemplated compounds can be formulated in admixture with pharmaceutically acceptable carriers. As an example but not exclusively, contemplated compounds can be administered orally as pharmacologically acceptable salts, or intravenously in a physiological saline solution (e.g., buffered to a pH of about 7.2 to 7.5). Conventional buffers such as phosphates, bicarbonates or citrates can be used for this purpose. Of course, one of ordinary skill in the art may modify the formulations within the teachings of the present disclosure to provide numerous formulations for a particular route of administration.

In particular, contemplated compounds may be modified to render them more soluble in water or other vehicle that, for example, may be easily accomplished with minor modifications (e.g. salt formulation, esterification, etc.) that are well within the ordinary skill in the art. It is also well within the ordinary skill of the art to modify the route of administration and dosage regimen of a particular compound or formulation in order to manage the pharmacokinetics of the present compounds for maximum beneficial effect in a patient or subject.

Also in particular, contemplated compounds may be prepared for delivery in tablet, capsule, pill or solution form, including any form that can deliver a controlled release of these compounds.

Similarly, it should be appreciated that while some claims recite components of formulations of invention embodiments, one of skill in the art will comprehend that other constituents, while pharmacologically inactive or inert in the context of the presently disclosed technology, might be a part of the formulation. Such inactive constituents include, as examples, excipients, binders, coatings, absorption enhancers, penetration enhancers, transport enhancers, stabilizers, chelators, buffers, carriers, clearance modifiers, emulsifying agents, antioxidants, preservatives, sugars, salts, cellulose, dyes, flavoring agents and any other inactive ingredients that are considered generally recognized as safe.

In certain pharmaceutical dosage forms, prodrug and derivative forms of contemplated compounds may be formed for various purposes, including reduction of toxicity, increasing the organ or target cell specificity, etc. Among various prodrug and derivative forms, acylated (acetylated or other) derivatives, pyridine esters and various salt forms of the present compounds may be advantageous. One of ordinary skill in the art will recognize how to readily modify the present compounds to prodrug and other forms to facilitate delivery of active compounds to a target site within the host organism or patient. One of ordinary skill in the art will also take advantage of favorable pharmacokinetic parameters of the prodrug and other forms, where applicable, in delivering the present compounds to a targeted site within the host organism, subject or patient to maximize the intended effect of the formulation.

Similarly, it should be appreciated that contemplated compounds may also be metabolized to their biologically active form (e.g., via hydroxylation, glycolsylation, oxidation etc.), and all metabolites of the compounds herein are therefore specifically contemplated. In addition, contemplated compounds (and combinations thereof) may be administered in combination with yet further antiviral and/or antibacterial agents. Suitable additional drugs therefore include but are not limited to various antibiotics (e.g., beta-lactam antibiotics, tetracycline antibiotics, oxazine antibiotics, etc.), various antiviral compounds (e.g., polymerase inhibitors), and/or compounds that stimulate the immune system.

It is to be understood that such descriptions or subject matter are merely exemplary, and that in fact many other descriptions, examples, methods, procedures and practices can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” or “coupled” such that the desired functionality is achieved. Hence, any two or more methods, procedures or practices herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of condition, event, injury, damage or pathology components. Likewise, any two or more components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two or more components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to, practices of embodiments of the invention required under different conditions, practices of embodiments of invention requiring different routes or methods of administration, practices of embodiments of invention requiring repeated administration for varying periods of time or logically interacting or logically interactable components to achieve the desired functionality.

In a general sense, those skilled in the art will recognize that the various aspects described herein which could be implemented, individually or collectively, by a wide range of methods, procedures or practices, or any combination thereof, can be viewed as being composed of various types of “formulation.” Consequently, as used herein “formulation” includes, but is not limited to, two compounds selected from gabapentin, progesterone, aprepitant and lithium, three compounds selected from gabapentin, progesterone, aprepitant and lithium or all four compounds selected from gabapentin, progesterone, aprepitant and lithium. Those having skill in the art will recognize that the subject matter described herein may be implemented in a method, procedure or practice as described herein, or some combination thereof.

As examples, the formulations, methods, procedures or practices of certain embodiments of the invention include many combinations and permutations thereof with respect to the nature of the individual formulations, and their relative methods, procedures or practices, can vary in operation by the relative methods, procedures or practices.

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the embodiments herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein.

Those skilled in the art will recognize that it is common within the art to describe methods, procedures or practices in the fashion set forth herein, and thereafter use standard practices to integrate such described methods, processes or procedures to reduce or prevent the development or the risk of development of neuropathology as a result of traumatic injury. That is, at least a portion of the methods, procedures or practices described herein can be integrated into reducing or preventing the development or the risk of development of neuropathology as a result of traumatic injury via a reasonable amount of experimentation. Those having skill in the art will recognize that typical methods, procedures or practices generally include those described herein. A typical method, procedure or practice may be implemented utilizing any suitable commercially available instrument, tool or device, such as any typically found in a medical facility or health delivery context or venue, and available to those typically familiar with methods, procedures or practices generally applied by those skilled in the art.

With respect to the use of substantially any plural or singular terms herein, those having skill in the art can translate from the plural to the singular or from the singular to the plural as is appropriate to the context or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.

Furthermore, it is to be understood that the invention is defined by the appended claims, and by the many claims that could be supported by the present specification. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.

It will be further understood by those within the art that virtually any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or practices, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. It is also to be understood that the terminology employed in the Detailed Description sections of this application is for the purpose of describing particular embodiments. It is also contemplated that any optional feature of the inventive variations described herein may be set forth and claimed independently, or in combination with any one or more of the features described herein. Moreover, in interpreting the disclosure, all terms should be interpreted in the broadest possible manner consistent with the context of the disclosed technology. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced.

Thus, many specific compositions, procedures and methods of the present “Pharmaceutical Formulations For The Treatment And Prevention Of Trauma-Induced Neuropathology And Neurodegeneration” have been disclosed and exemplified. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein, or from the spirit of the invention. The inventive subject matter, therefore, is not to be restricted except in the spirit of the disclosure.
